Letters Patent No. 101,267, dated March 29, 1870.

IMPROVE!) SPRINGMDEID.

The Schedule referred to in these Letters Patent and making par?. of the name To all persons to whom these presents may come:

Be 'it known that I, Livnnns HULL, of' Charlestown, of the county' of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Spring-Beds or Bed-Bonndatons; and do hereby declare the same to be fully described in the following specification, and represented in the accomallel to each other, at u. suitable distance apart, and.

tcnoned into two parallel side bars B B, such bars con stituting a frame.

Each of the bars A A is formed with a series of abut-ments, aa, extended from its inner side, there being between each abutment and that next to it a wedgeshaped recess, b.

'Each abutment on its top isy channeled or grooved Alengthwise across such, to receive the middle or hinge part c'of one ot' the compensation springs, O. Such part oi' the spring is to be placed in such groove 'and kept in place by a cap plate, D, extending over the part c, and bolted to the bar A.

Each ofthe springs consists of a wire bent twice at a right anglefnear` its middle, viz,I at d d, as shown in Figure 6, after' which each portion or leg d' e is bent or'turned, at or near its middle, around a. cylinder, so lestohave one or more helical coils introduced into, 'sishown at f, in the drawings. y

-Next the two ends or legs of the spring or parts g 'are to be. inserted, and fixed in asaddle or block, h,

provided with a pivot or stud, "L, extended upward from it.

A series ci' the springs (l is applied to each of the bars A A, in marmer as above described, each spring being extended beyond the ends` of its supporting abutment, in order that the legs of the spring may have proper vertical play, without interruption from the abutment.

A series of slats, D D, is supported by the several springs or their saddleblocls and the studs thereof, each slat being made to extend over one spring of each of the barsA A, and to receive the stud of such spring intobne of two holes, K K, made in the slat, the whole being as represented in the drawings.

Each spring, while being depressed by a. weight on the slat, will operate to cause the saddle-block to descend nearly, if not entirely in a vertical line, there being a double action on each leg of the spring, by which the spring is rendered very etiicient.

I claim- The combination and arrangement of thepivotcd or pivotal saddle-block, h, with a spring, C, made as described.

Also, the combination and arrangement of the two groovcd abutments, a, a, and the cap-plates D D thereof', ,with the bars A A and the springs C C, oo nstrnctcd and combined with pivotal saddlefbl'ocks h h, and applied to each slat D, as set forth.

Also, the improved bed-foundation, as composed of the springs C, made and arranged as described, the separate pivotal saddle-blocks h, 'the slats D, and the frame-bars A A. B B, provided with the grooved abi-1tv ments and cap-plates to the transverse bars, as s et forth.
